The Possession (formerly titled The Dibbuk Box) just gave us the chills, and that's hard to do these days. Watch as a little girl finds a brand new box and unleashes a demon INSIDE OF HER. No seriously, most of the trailer is this creature trying to climb its way outside of a little girl. Yikes! Color us intrigued! The Possession is in theaters on August 31 — here's a synopsis:

Based on true events, ‘The Possession' is the terrifying story of how one family must unite in order to survive the wrath of an unspeakable evil. Clyde (Morgan) and Stephanie Brenek (Sedgwick) see little cause for alarm when their youngest daughter Em becomes oddly obsessed with an antique wooden box she purchased at a yard sale. But as Em's behavior becomes increasingly erratic, the couple fears the presence of a malevolent force in their midst, only to discover that the box was built to contain a dibbuk, a dislocated spirit that inhabits and ultimately devours its human host.
